Google Antigravity Workflow Automation: Custom Tasks, Hooks & AI-Powered Pipelines

Automation is where Google Antigravity shines. Combine built-in tasks with Gemini 3 AI to create powerful development workflows that save hours of manual work.

Workflow Automation Basics

What Can Be Automated?

• Build processes - Compile, bundle, optimize
• Code quality - Lint, format, type-check
• Testing - Unit, integration, E2E tests
• Deployment - Staging, production releases
• Documentation - Generate docs, update README
• AI tasks - Code review, refactoring, generation

Custom Tasks

Task Configuration

// .antigravity/tasks.json
{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Build Project",
      "type": "shell",
      "command": "npm run build",
      "group": {
        "kind": "build",
        "isDefault": true
      },
      "problemMatcher": ["$tsc"]
    },
    {
      "label": "Run Tests",
      "type": "shell",
      "command": "npm test",
      "group": "test"
    },
    {
      "label": "Deploy Staging",
      "type": "shell",
      "command": "npm run deploy:staging",
      "dependsOn": ["Build Project", "Run Tests"]
    }
  ]
}

Compound Tasks

Chain tasks together:

{
  "label": "Full CI",
  "dependsOn": [
    "Lint",
    "Type Check",
    "Build Project",
    "Run Tests"
  ],
  "dependsOrder": "sequence"
}

AI-Powered Hooks

Pre-Commit Hooks with AI

// .antigravity/hooks/pre-commit.js
module.exports = {
  async run(context) {
    const { stagedFiles, gemini } = context;
    
    // AI review staged changes
    for (const file of stagedFiles) {
      const diff = await context.getDiff(file);
      
      const review = await gemini.analyze({
        prompt: `Review this diff for potential issues:
        - Security vulnerabilities
        - Performance problems
        - Code style violations
        
        ${diff}`,
        mode: 'quick'
      });
      
      if (review.hasBlockingIssues) {
        return {
          success: false,
          message: review.summary,
          details: review.issues
        };
      }
    }
    
    return { success: true };
  }
};
